Nelson Mandela, former president of South Africa and Nobel Peace Prize winner, has died. During his long life, Mandela inspired countless individuals. Here is a collection of quotes that personify his spirit:

1) “Difficulties break some men but make others. No axe is sharp enough to cut the soul of a sinner who keeps on trying, one armed with the hope that he will rise even in the end.”

2) “It always seems impossible until it’s done.”

9) “I learned that courage was not the absence of fear, but the triumph over it. The brave man is not he who does not feel afraid, but he who conquers that fear.”

10) “For to be free is not merely to cast off one’s chains, but to live in a way that respects and enhances the freedom of others.”

11) “Resentment is like drinking poison and then hoping it will kill your enemies.”

12) “Lead from the back — and let others believe they are in front.”

13) “Do not judge me by my successes, judge me by how many times I fell down and got back up again.”

14) “I hate race discrimination most intensely and in all its manifestations. I have fought it all during my life; I fight it now, and will do so until the end of my days.”

15) “A good head and a good heart are always a formidable combination.”
